NVIDIA GeForce GTX 680 Review: Retaking The Performance Crown
NVIDIA’s cards have always done well at Battlefield 3, which puts the Radeon HD 7900 series in a bad position from the beginning. Short of the GTX 680’s massive lead in the Portal 2 bonus round, this is the single biggest victory for the GTX 680 over the 7970, beating AMD’s best by 28% at 2560, and by continually higher amounts at lower resolutions. Based on our experience with BF3 I’d hesitate to call the 680 fully fluid at 2560 as large firefights can significantly tear into performance relative to Thunder Run, but if it’s not fully fluid then it’s going to be very, very close.
What’s also interesting here is that once again the GTX 680 is doing very well compared to the dual-GPU cards. The GTX 590 and 6990 never pull away from the GTX 680, and at 1920 with FXAA the GTX 680 finally squeaks by and takes the top of the chart. Performance relative to the GTX 580 is also once again good for that matter, with the GTX 680 beating its predecessor by 48% at almost every resolution.
Starcraft II
Our next game is Starcraft II, Blizzard’s 2010 RTS megahit. Much like Portal 2 it’s a DX9 game designed to run on a wide range of hardware so performance is quite peppy with most high-end cards, but it can still challenge a GPU when it needs to.
While AMD tends to suffer in Starcraft II at lower resolutions, at 2560 we tend to get a good brawl and the GTX 680 doesn’t disappoint. Here it leads the 7970 by 13% and leads the GTX 580 by 39%.
The Elder Scrolls V: Skyrim
Prior to the launch of our new benchmark suite, we wanted to include The Elder Scrolls V: Skyrim, which is easily the most popular RPG of 2011. However as any Skyrim player can tell you, Skyrim’s performance is CPU-bound to a ridiculous degree. With the release of the 1.4 patch and the high resolution texture pack this has finally been relieved to the point where GPUs once again matter, particularly when we’re working with high resolutions and less than high-end GPUs. As such, we're now including it in our test suite.
Skyrim presents us with an interesting scenario. At anything less than 2560 we’re CPU limited well before we’re GPU limited, and yet even though we’re CPU limited NVIDIA manages to take a clear lead while the 680 still finds room to push to the top. For whatever the reason NVIDIA would appear to have significantly less driver overhead here, or at the very least a CPU limited Skyrim interacts with NVIDIA’s drivers better than it does AMD’s.
In any case 2560 does move away from being CPU limited, but it’s not entirely clear whether the difference we’re seeing here is solely due to GPU performance, or if we’re still CPU limited in some fashion. Regardless of the reason the GTX 680 has a 10% lead on the 7970 here.
Civilization V
Our final game, Civilization 5, gives us an interesting look at things that other RTSes cannot match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry, driver command lists for reducing CPU overhead, and compute shaders for on-the-fly texture decompression.
Remember when NVIDIA used to sweep AMD in Civ V? Times have certainly changed in the last year, that’s for sure. It only seems appropriate that we’re ending on what’s largely a tie. At 2560 the GTX 680 does have a 4% lead over the 7970, however the 7970 reclaims it’s lead at the last possible moment at 1920. At this point we’ve seen the full spectrum of results, from the GTX 680 losing badly to winning handily, and everything in between.
On a final note, it’s interesting to see that the GTX 680 really only manages to improve on the GTX 580’s performance at 2560. At 1920 the lead is only 8%, and at 1680 we’re just CPU limited. Haswell can’t get here soon enough.

NVIDIA GeForce GTX 680 Review: Retaking The Performance Crown
Battlefield 3
Its popularity aside, Battlefield 3 may be the most interesting game in our benchmark suite for a single reason: it’s the first AAA DX10+ game. It’s been 5 years since the launch of the first DX10 GPUs, and 3 whole process node shrinks later we’re finally to the point where games are using DX10’s functionality as a baseline rather than an addition. Not surprisingly BF3 is one of the best looking games in our suite, but as with past Battlefield games that beauty comes with a high performance cost
